I don't think such a device would ever be made, and even if it did, it would be kinda silly. You can get a cheap portable TV if you want to, tho the quality is generally terrible. Now, Tivo on the otherhand is going to incorporate iPod and PSP connectivity in the next firmware release. So you can effortlessly transfer taped TV shows to your iPod. It won't be live, but the quality would be great, and no more junk to carry around.
